Evaluating Nano Calcium Hydroxide for Treating Infected Tooth Roots

Evaluation of the Antibacterial Potential of Nano Calcium Hydroxide as an Intracanal Medication: A Randomized Clinical Trial

Phase2; Phase3 Interventional British University In Egypt · NCT06196515

This study is testing a new gel form of Nano Calcium Hydroxide to see if it can better fight bacteria in infected tooth roots compared to traditional treatments for people with tooth infections.

What this trial studies

This study aims to assess the antibacterial effectiveness of Nano Calcium Hydroxide as an intracanal medication during the primary endodontic treatment of permanent molars. It involves synthesizing a hydrogel that transforms from liquid to gel at body temperature, which will be compared to both Nano and conventional Calcium Hydroxide in paste form. The study will quantitatively evaluate bacterial reduction by analyzing samples taken from the root canal before and after treatment in patients with apical periodontitis. The goal is to determine the most effective form of calcium hydroxide for improving dental outcomes.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 21-49 with a single permanent molar showing signs of apical periodontitis.

Not a fit: Patients who are pregnant, immunocompromised, or have complicated systemic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatments for endodontic diseases, reducing infection rates and improving patient outcomes.

How similar studies have performed: Other studies have shown promise in using nano-formulations for antibacterial purposes, suggesting potential success for this novel approach.
